2001 Virage CDI - Just Bought and new one...why so many part #'s?

I just bought a new CDI for my 2001 700cc Virage. I took some pictures of it for reference so you can see the correct model #'s. It has several #'s on it that are crossed out so maybe some of yall can shed some light on the matter...is this just a refurb or what?

PVL would manufacture the CDI in batches with a production part number for Polaris, then ship the CDI to Polaris factory. Sometimes Polaris would need to revise the initial CDI programming (mostly the spark advance curve) before using them in certain models or engines.

When they did so the original part number would be crossed out and the revised part number hand marked. In this case it looks like the CDI got reprogrammed twice.
